    Hey, Jeff. You should definitely mention your Patreon in your videos because I think a lot of people watching don't even know you got one and would love to contribute. I think you truly deserve something in return for saving all of our asses. Thanks, man!

    Mr.Hanson ...I would say it would be good to see if you do a main topic such as this then you divided it into several calculation involving different shape such as triangle, right angle triangle , circle etc. We could see if there's any extra calculation when trying to calculate it and also different scenario like a triangle shape but it has extra length on the beam like in this video

    • @adamgulamhusein8768
      @adamgulamhusein8768 2 роки тому

      M is negative because it is going clockwise. By convention, this is typically negative. 200 is negative for the same reason.

    The value of the moments are the same regardless of whichever side of the beam you pick after cutting the beam but you will get a different direction (counterclockwise, clockwise,..) so when asked to express the direction of the moment at a point, which direction do we write ?

    • @windyjay4627
      @windyjay4627 3 роки тому

      I have a very very good feeling that if it is negative, still write it as clockwise. If positive, then counterclockwise. I think when analyzing the beam you don't use the standard directions as the values of each side of the beam wont be equal (opposite signs (which makes sense since you are analyzing opposite sides of a point on a beam) ), hence the new direction rules. But when writing the final answer, you return back to using the conventional direction rules.

    why at 12:01 and 12:26 that V is in negative sign and M and 200 all have a negative sign ?

  • @YehanDeSilva-x1o
    @YehanDeSilva-x1o Рік тому

    When you get negative values for v does that mean it’s acting on the opposite direction? Are the directions the same even if you choose to go from the left/right?

    • @balajihariharan7175
      @balajihariharan7175 4 роки тому +1

      there is a upward positive force By, so to balance it our V has to be equal and negative. And M is in the clockwise direction, clockwise moment is negative

    • @camhowden1445
      @camhowden1445 3 роки тому +1

      I think he cut it at the 7ft line. Around 7:00 he explained that he'll be cutting the beam and choosing a side like the method of sections. That's also why we need the positive sign conventions depending on which side we choose.
      Hope this helped!

    What changes Ay to 136.8 rather that it also being 113.2, I can solve for B but I don't know what is being done to it to make A, he says -250 but when I look I get minus 225, and I don't know where that would come form. 10:01 thanks

    • @_AnUnoriginal_
      @_AnUnoriginal_ 4 роки тому +2

      It's the equilibrium for fy, so the equation is Ay + By - 100 - 150 = 0 since those are all the variable for fy. From there, you just move the equation to Ay = 250 - By. And you should get Ay

    Can someone help me understand why Ax = 0?
    Thanks!

    • @hussam-ym
      @hussam-ym 3 роки тому

      Hey, if you try to construct an equilibrium equation in the x direction ( Fx), you will only find Ax there, which means Ax=0, in other words there is no other forces in the x direction that Ax would balance and so there is no x-component for A.

    • @hussam-ym
      @hussam-ym 3 роки тому

      Also, the reaction at B does not have an x component because it is a roller, refer back to Prof Hanson's video on supports and the reaction forces they give. So that leaves us with only Ax in the x direction, and due to equilibrium sum of forces in the x=0, Ax=0.
